间接修改重载属性App \ Dossier :: $ program无效 [英] Indirect modification of overloaded property App\Dossier::$program has no effect

问题描述

早上好，我在后端有此代码(尝试在MONGO中更新此值) http://prntscr.com/j03gh4

Good Day I have this code on backend (trying to update this value in MONGO) http://prntscr.com/j03gh4

$dossier=Dossier::where('_id',(int)$request->input('dossier_id'))->first();
//var_dump($request->input('value'));
$dossier->program[$request->input('program')]['cities']
 [$request->input('city')]['services']
 [$request->input('service')][$request->input('name')]=$request->input('value');
$dossier->save();

但我收到此异常 http://prntscr.com/j03h0s

对重载属性App \ Dossier :: $ program的间接修改无效

Indirect modification of overloaded property App\Dossier::$program has no effect

该如何解决这种情况?

推荐答案

问题是，调用$dossier->program并没有直接在Eloquent类型模型中直接访问该属性，而是调用了__get方法.

The problem is that calling $dossier->program does not actually access the property directly in Eloquent type models but rather calls a __get method.

该get方法不会返回对该属性的引用.您应该做的就是获取原始属性，对其进行修改，然后放回原处:

That get method does not return a reference to the property. What you should do is grab the original property, modify it and then put it back:

$dossier=Dossier::where('_id',(int)$request->input('dossier_id'))->first();
$originalProgram = $dossier->program;
$originalProgram[$request->input('program')]['cities'][$request->input('city')]['services'][$request->input('service')][$request->input('name')]=$request->input('value');
$dossier->program = $originalProgram;
$dossier->save();
